Beschreibung
Zusammenfassung:	A photoelectric conversion apparatus includes an avalanche diode (APD) disposed in a semiconductor layer, and a first wiring structure, the APD including a first semiconductor region disposed at a first depth, a second semiconductor region disposed at a second depth deeper than the first depth, a third semiconductor region disposed in contact with an end portion of the first semiconductor region, a first wiring portion connected to the first semiconductor region, and a second wiring portion connected to the second semiconductor region, wherein a first pad configured to apply a first voltage to the photoelectric conversion apparatus is disposed in the first wiring structure, and wherein in the planar view, at least a part of a boundary portion between an insulating film facing the first wiring portion and the second wiring portion overlaps the third semiconductor region and does not overlap the first semiconductor region.
